CVE-2026-53168

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. The fusenotify function, specifically the FUSENOTIFYSTORE and FUSENOTIFYRETRIEVE operations, allows the FUSE daemon to write or read pagecache contents. When these operations are performed on directories configured wit...

CVE-2026-53172

A flaw was found in the Linux kernel's accel/ethosu component. An incorrect mask used when processing the NPUSETIFMREGION command allows a local userspace caller to provide an out-of-bounds region index. This can lead to an out-of-bounds write, corrupting adjacent kernel heap data...

CVE-2026-53219

A flaw was found in the Linux kernel's netfilter xtables component. This vulnerability allows for information disclosure due to improper handling of percpu counter pointers during the copying of rule entry headers to userspace. A local attacker could exploit this by causing a fault in a userspace...

CVE-2026-53169

The CVE affects the Linux kernel driver path accel/ethosu and specifically rejects NPU_OP_RESIZE commands from userspace. The root cause is a placeholder WARN_ON(1) that fires for DRM_IOCTL_ETHOSU_GEM_CREATE, allowing unbounded kernel log spam and, if panic_on_warn is set, a potential denial-of-s...

EUVD-2026-39260

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: reject NPUOPRESIZE commands from userspace NPUOPRESIZE is a U85-only command that the driver does not yet implement. The existing WARNON1 placeholder fires unconditionally whenever userspace submits this command via...

EUVD-2026-39259

In the Linux kernel, the following vulnerability has been resolved: fuse: reject fusenotify pagecache ops on directories The operations FUSENOTIFYSTORE and FUSENOTIFYRETRIEVE allow the FUSE daemon to actively write/read pagecache contents. For directories with FOPENCACHEDIR, the pagecache is used...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15, and Linux 6.1

An integer overflow flaw was discovered in the Linux kernel. This issue causes the kernel to allocate skbsharedinfo in the user space, which can be exploited in systems without SMAP protection, as skbsharedinfo contains references to function pointers...

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: uaudio: do not allow userspace to block driver unbind In the unbind callback for fuac1 and fuac2, a call to sndcardfree via gaudiocleanup will disconnect the card and then wait for all resources to be released, which...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: nvme: fixed memory allocation in nvmeprreadkeys nvmeprreadkeys takes numkeys from userspace and uses it to calculate the allocation size for rse via structsize. The upper limit is PRKEYSMAX 64K. A malicious or buggy userspace...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: powerpc/tm: Fixed corruption in user space r13. The commit cf13435b730a “powerpc/tm: Fixed corruption in user space r13” fixes a problem in treclaim, where a SLB miss can occur on threadstruct-ckpt regs, when SCRATCH0 is active a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RISCV: Vector: Fixed the context saving/restoring with xtheadvector. Previously, only v0-v7 were correctly saved/restored, and the context of v8-v31 was corrupted. Now, v8-v31 are correctly saved/restored to avoid breaking the us...
